I am pretty new to Office 365, but I have a business premium licence which includes also Sharepoint.
I created a new site, based on a topic communication template, where I would like to add a new page as Wiki Page Library, where I can put documents and knowledge based related to that site.
However I do not know how? It should be possible to add it as a new app according the following article from Microsoft support: Create and edit a wiki
But my issue is that I do not see any Wiki Page Library when clicking on Add an app. And I do not think it is a permission issue as I am a global administrator of Office 365.
I've spent hours on Google trying to find solution, looking into different options in admin section of Office 365 and Sharepoint, but I am not able to find Wiki Page Library...
Any advice?
